ELECTRIC BATTERY.

Specification of Letters Patent.

Patented Mar. 7, 1911.

Application filed July 13, 1910. Serial No. 571,851.

To all whom 'it may concern:

Be it known that I, CARL JAEGER, a subject of the Emperor of Germany, and a resident of the city of Seattle, in the county of King and State of l/Vashington, have invented certain new and useful Improvements in Electric Batteries, of Which the following is a specification.

The present invention has particular reference todry cells, and the primary aim thereof is an improved closure for the cell Wherein provision is made for introducing fluid to moisten the body.

The invention resides in certain novel eatures in the construction "and arrangement 'of parts as set forth in the following description and defined in the claims.

In the accompanying` drawing, wherein similar reference numerals designate corresponding parts throughout: Figure 1 is a longitudinal section of a cell embodying the features of' my invention. Fig. 2 is a transverse section thereof, and Fig. 3 is a perspective of the fluid chamber in broken section. 'l

With reference to Figs. 1 and 2, numerals 3, fi indicate the ltvvo electrodes, With the terminals 4.3,* 5 respectively. 6 is the case or holder, `and 7 thefilling mass or bodywhicl is introducedin al dry state into the case o r holderand subsequently moistened When desiret-o use'the cell. Electrode` 3 comprises a perforated zinc plate extending in the filling mass or body and held in spaced relations to the electrodeA t and' the lcase or holder by means of disks 3v of comminuted4 My improved closure embodies a chamber 8 of variable capacity conveniently comprising telescopic tube section. 9 10, and heads therefor, as 9 10 in which apertures are i rovided to receive electrode 4. Seated in vcad 9 is tubular cork 11 Whose passage way is normally closed by a glass stopper 12 havin ailexible puller 13 attached thereto. 5 Cham er 8 and case holder 6 are preferably ized to render it moisture proof.

In closing the cell I place a perforated felt disk or blanket 14: over the filling mass or body and cover the same With a layer 15 of asphalt. Chamber 8, subsequently adjusted to receive when filled the requisite quantityoi Water or other liquid for moistening the filling mass, is then inserted in the 'case or holder against the asphalt and covered with a layer 16 of suitable sealing material.

When desired to use the cell, stopper 12 is Withdrawn and chamber 8 illed With the moistening liquid. A nail cr other pointed instrument is then inserted throughthe passageway in cork 11 and driven through the bottom head of the chamber and underlying layers of asphalt and felt to provide a channel :tor leading the liquid to the body of the cell. rlhe stopper is then seated in the cork and the cell is ready for use.

Having thus described my invention, what l claim-as new, and desire to secure by Letters Patent of the United States of America, 1s:

1. ln a cell of a dry battery, a liquid holder formed of telescoping sections, one of said sections being provided With a destructible portion, the other of said sections being formed With\ an opening opposite to the destructible portion of said'first section,l for the purposey specified. v

2. In a cell of a dry battery, inlcombination With the case thereof, a closure therefor comprising a liquid holder of a destructible nature, and a covering for said closure provided with an opening through which a destroying agent for said closure can be inserted. j

3. In a cell of a dry battery in combination with the case, a closure for saidcase comprising a normally sealed liquid holder, and a perforated .felt blanket arranged be- 'neath said closure 'and having a covermg-of asphalt. i l

composed of pasteboard suitably parafnnature formed vwith an opening, a covering `seal for said closure, a cork seated in the -formed with a. passage-Way, a stopper in th' 4. In a cell of a. dry battery, in combinapassagef way of said cork, and a flexible f tion with the case, a closure for 4said case puller attached to said stop er. comprising a liquid holder of a destructible Signed at Seattle, llvashlngfton, this 5th day of July 1910.
